Luck of the Draw buff and 4.0.6

GC just made the announcement of having variable Luck of the Draw buff. Currently we have just a 5% buff. However in 4.0.6 he is instigating a change that allows for up to 15% buff for 3 or more random pug members. Do you think we should change the
buff to 15% or do you think we should keep the buff as is?
